Description
Ground
Active-low reset output. RESETN remains low while VDD is
below the reset threshold and for tTP after VDD rises above
the reset threshold. RESETN is open-drain on the AS1903
and push-pull on the AS1901.
Active-high reset output. RESET remains high while VDD is
below the reset threshold and for tTP after VDD rises above
the reset threshold.
